I've never had such panic overcome me as I did descending the middle fork of Leprechaun Canyon. When they say this is narrow, they are not kidding for one second! I am 6'4 and 220 pounds. It got so tight that the only way I could get through was to chimney up. There were parts I was unsure how I could possibly find a way through, but with patience and help of friends I made it through. I have done many slot canyons, but for some reason this was the one that did me in mentally. 15 pounds lighter and I'll do it again! Time for the left and right forks! Here is a video to give you an idea of how tight.

All three forks of Leprechaun in one day. Not difficult to do at all when exiting at the junction.

Be careful because the brief descriptions provided here lack any detail. These are not difficult canyons, but are far from easy walk through either. Also, the easiest access (sans driving) is to walk up the slickrock from the highway.
